一个文件夹中有一百万或以上的文件，用于包含（缓存） [英] 1 million or more files in one folder, for include (cache)

问题描述

我有一个'理论'的问题，看看我正在计划的解决方案是否合理：

我有一个脚本，可以读取大量的数据从数据库中取出设置，配置等，并建立起来（每个注册用户）。我不会进入太多的细节为什么或什么。

我的想法是，我实际上只能做一次，并创建 .inc 文件与用户的ID一起缓存。如果用户改变了某些东西，文件将被重新创建。

但是现在，假设我这样做了，有1000万个，甚至更多的文件。我会遇到问题，而包括这些文件？ （总是一个特定的文件，而不是每个文件一次）。这是一个很好的主意，或者我只是强调更多的服务器与此？

我打算把一切都在同一个缓存文件夹 - 将我有性能改进，如果我把该文件夹分成多个？

感谢您的帮助。

解决方案

您将受到文件系统的限制。无法在文件夹中找到多个文件。你可以这样做：

1. 哈希文件名： file1.php 变成 3305d5836bea089f2a1758d8e89848c8


2. 将散列分成若干部分： 3/3/0/5 / d / 5836bea089f2a1758d8e89848c8


3. 已完成

I have a 'theoretical' question, to see if a solution I'm planing makes sense or not:

I have a script that reads a lot of data out from the Database, with settings, configuration, etc - and builds that togheter (for every registered user). I wont go into too much details why or what exactly.

My Idea was, that I could actually do that only once and create a .inc file, with the ID of the user, to cache it. If the user changes something, the file will be recreated of course.

But now, lets suppose I do that, with 1'000'000 - or even more files. Will I encounter issues, while including those files? (always one specific file, not every file at once). Is that generaly a good idea, or am I just stressing the server even more with this?

And I'm planing to put everything in the same cache folder - will I have performance improvements, if I split that folder up into multiple ones?

Thanks for the help.

解决方案

You will be limited by the file system. It's not possible to reach that many files in a folder. You can do something like this:

1. Hash the filename: file1.php becomes 3305d5836bea089f2a1758d8e89848c8
2. Split the hash in several parts: 3/3/0/5/d/5836bea089f2a1758d8e89848c8
3. It's done
